Underwater Acoustic Ranging Between Smartphones
Tuochao Chen, Justin Chan, Shyamnath Gollakota
We present a novel underwater system that can perform acoustic ranging between commodity smartphones. To achieve this, we design a real-time underwater ranging protocol that comput…
Testing a Drop of Liquid Using Smartphone LiDAR
Justin Chan, Ananditha Raghunath, Kelly E. Michaelsen +1
We present the first system to determine fluid properties using the LiDAR sensors present on modern smartphones. Traditional methods of measuring properties like viscosity require…
Identifying Pediatric Vascular Anomalies With Deep Learning
Justin Chan, Sharat Raju, Randall Bly +2
Vascular anomalies, more colloquially known as birthmarks, affect up to 1 in 10 infants. Though many of these lesions self-resolve, some types can result in medical complications o…
DeepSense: Enabling Carrier Sense in Low-Power Wide Area Networks Using Deep Learning
Justin Chan, Anran Wang, Arvind Krishnamurthy +1
The last few years have seen the proliferation of low-power wide area networks like LoRa, Sigfox and 802.11ah, each of which use a different and sometimes proprietary coding and mo…
Contactless Cardiac Arrest Detection Using Smart Devices
Justin Chan, Thomas Rea, Shyamnath Gollakota +1
Out-of-hospital cardiac arrest (OHCA) is a leading cause of death worldwide. Rapid diagnosis and initiation of cardiopulmonary resuscitation (CPR) is the cornerstone of therapy for…
Surface MIMO: Using Conductive Surfaces For MIMO Between Small Devices
Justin Chan, Anran Wang, Vikram Iyer +1
As connected devices continue to decrease in size, we explore the idea of leveraging everyday surfaces such as tabletops and walls to augment the wireless capabilities of devices.…
